Thought I would share that Noomle now has made mobile sites for each domain which is hosted through them. Generally, if a mobile visitor hits your site sometimes it won't look that great (if you your a mobile user yourself you'll know what I mean) because the site isn't setup to cater towards mobile users. Thats changed now, so you can properly monetize your mobile visitors through PPC or affiliates. Take a look for yourself, its great - http://forums.noomle.com/showthread.php?t=2054
Here's some great examples of the mobile templates that are being used. These are being reported as great PPC models by those who are using them. Checked it out for yourself, don't just stick to the same old model if your not happy with your results!
